Introducing Namadock: Docker‑first bootstrap for Namada nodes
Hi Namada community,
I’m happy to present Namadock, a Docker‑centric bootstrap image that applies Twelve‑Factor App principles to running a Namada node.
Why this matters
- RPC is the heart of Namada infra – if a validator’s RPC crashes or lags, every explorer, wallet and dApp, indexers suffers. Reliable node management is critical for network health.
- One‑command recovery – bring a fresh node online (or recover from disaster) in seconds using a snapshot.
- Developer‑friendly – spin up a local node for testing without wrestling with system packages or source builds.
- Open door for future tooling – Namadock’s environment‑based configuration lays the groundwork for automated upgraders and plug‑and‑play monitoring (examples below).
Note: only the Namadock container exists today. The updater and monitor shown below are ideas under active exploration.
Quick start
services:
node:
image: ghcr.io/mellifera-labs/namadock:v101.1.2-1beta
container_name: namada_node
ports:
- "21257:26657" # RPC
- "21256:26656" # P2P
- "21260:26660" # Prometheus
- "21258:26658" # CometBFT
volumes:
- /home/ubuntu/namadock-data:/home/namada/.local/share/namada
- /home/ubuntu/namadock-masp:/home/namada/.masp-params
environment:
- RUN_FROM=snapshot
- SNAPSHOT=https://server-5.itrocket.net/mainnet/namada/namada_2025-07-26_2919562_snap.tar.lz4
- EXTERNAL_ADDRESS=IP:21260
- PEERS=no
command: ["ledger", "run"]
Run docker compose up -d
and the node will restore from the snapshot and start syncing—no extra steps.

Looking forward to your thoughts!
Future ideas (feedback welcome)
Automatic upgrades
Namada still doesn’t have an automatic update solution—this initiative introduces an automatic updater.
# 1️⃣ Scheduled upgrades — concept
services:
node: # as above
namada-updater:
image: ghcr.io/mellifera-labs/namada-updater:edge
environment:
CONFIG: |-
[
{
"height": 5_000_000,
"image": "ghcr.io/mellifera-labs/namadock:v101.2.2-1beta"
}
]
Furthermore, the updater can be configured to sync a full node from genesis, applying sequential upgrades during the initial sync to preserve the entire chain history.
Plug‑and‑play monitoring
Monitoring nodes and validators is essential—it’s a cornerstone of reliable Namada infrastructure.
Recent validator jails have underscored this issue.
A plug‑and‑play Docker image can make monitoring effortless: operators simply add a small config block to their docker-compose.yml
, and their node or validator is immediately covered.
# 2️⃣ Plug‑and‑play monitoring — concept
services:
node: # as above
namada-monitor: # <── not released yet
image: ghcr.io/mellifera-labs/namada_monitor:edge
environment:
- ALERT__STALL=5m
- ALERT__MISSED_BLOCKS=5
- VALIDATOR_ADDRESS=tnam...
- NODE_0_RPC=http://node:26657
- ALERT_ROUTE=telegram
- ALERT_TELEGRAM_TOKEN=<TOKEN>
- ALERT_TELEGRAM_CHAT_ID=<CHAT_ID>
- HEALTHCHECK=https://hc-ping.com/namada-node
I’ve already created a Prometheus exporter, but it requires Grafana, which adds another step. With this container, all you need is the environment block above—drop it into the Compose file and monitoring is live, whether your goal is to track a node or a validator.
How this all help increase quality of Namada infra
-
Higher RPC uptime – automatic container restarts and snapshot restores slash downtime after crashes
-
Smooth, timed upgrades – future updater sidecar can switch images at a target block without manual intervention
-
Standardized layout – fixed ports, paths, and env vars let monitoring/automation “just work” out of the box
-
Fast disaster recovery – RUN_FROM=snapshot re‑hydrates a node in minutes, keeping validators bonded and services current
-
Developer on‑ramp – docker compose up spins up a local chain for testing in under two minutes
-
Pre‑packaged monitoring – drop‑in alert container catches stalls, missed blocks, and health issues early
-
Easier decentralized hosting – container‑first design fits Akash, Flux, and other distributed clouds, spreading public RPC load
-
Consistent upgrade path for indexers – same Compose file can pin matching images for Namada‑indexer, MASP indexer, etc., preventing schema drift
-
Overall network reliability boost – fewer “RPC unavailable” errors, faster validator recovery, and more predictable upgrades improve the experience for wallets, dApps, explorers, and relayers
Questions for the community
- Does Namadock address real pain points for validators and developers?
- Should we invest time in building the updater and monitor sidecars?
- What additional features would improve node reliability or developer UX?
